Abstract
An electric-wear adjusting device of a motor vehicle disc brake is provided for adjusting friction surface wear on the brake linings and brake disc of the disc brake having. having a brake application device, preferably with a rotary brake lever. The adjusting device includes an electric motor, a gear mechanism, and an output element. The output element is connected rotationally fixed to a clamping sleeve. The clamping sleeve has inwardly projecting longitudinal ribs on an inner side configured to cooperate with axial grooves of a threaded plunger of a wear-adjuster spindle unit. Also provided is a corresponding disc brake having the electric wear-adjusting device, and a method for measuring and setting air play and measuring wear of a disc brake having the electric wear-adjusting device.
